Delete a file in java

[rahulJ james]

I need to delete a file in java.
I have the below code, but it doesnt work.

  
File f = new File(dirName + "filename.txt");
f.delete();
  

If I hardcode the directory name, it works.. How do I fix this problem which is because of single '\'

First check if it exists and what the absolutePath is. Compare that with what you expect.
Also delete() returns a boolean whether is was a success or not.

How about using

new File(dirName, "filename.txt");

This will let the API handle all the hard work for you.
